Re: [GSoC][PATCH v3 05/13] sequencer: add a new function to silence a command, except if it fails

Alban Gruin [off-list ref] writes:

This adds a new function, run_command_silent_on_success(), to
redirect the stdout and stderr of a command to a strbuf, and then to run
that command. This strbuf is printed only if the command fails. It is
functionnaly similar to output() from git-rebase.sh.

run_git_commit() is then refactored to use of
run_command_silent_on_success().

Looks good to me; it seems to cover the glitches pointed out in the
previous round well.
